A method of assisting the movement of a dog includes a carrying strap that is elongated and has a front end and a rear end. Each first dispersive element includes first and second light transmissive film materials. One of the sections in which the link housing is positioned when the toggle type mold clamping system is set in a lock-up state in which a movable half mold is in contact with a fixed half mold is specified by a combination of binary signals provided by switches. In a second embodiment, no symbol repetition is provided and variable length Walsh sequences are used to handle data rate variations. The transport stream is sent over the reverse link to base station transceivers.
